DESCRIPTION

Square Washer - Plain - M12x40x5 (Box=200)

(Price per unit)

Heavy square washers are thick steel washers with a large square profile designed to distribute bolt clamping force over a wider area. They are commonly used in timber and other soft materials where standard round washers may be pulled through under load.

Key points:

  • Wide square surface helps spread load and reduce pull-through in softer materials
  • Commonly used in timber construction such as deck framing, retaining walls, and general softwood structures
  • Square design helps prevent the washer from rotating within the material
  • Plain finish allows application of a variety of coatings. 
  • Available in a variety of finishes for different corrosion resistance needs

Note: For galvanic compatibility always pair the washer material to the bolt & nut: stainless bolt & nut to stainless washer, galvanised bolt & nut to galvanised washer.

Mixing materials can create corrosion & less durability in damp, wet environments.
